Factor 1 Plus
This range of thermal base layers are produced on seamless knitting machines and are designed to be snug fitting but not restrictive. They are knitted on different diameter machines for each size. The height of the waist and the length of the body are not as long as the Factor 1 range but they are still generous. Unisex leggings (no Fly) are only produced currently in this range.

Sub Zero Factor 1 Plus Long Sleeve Thermal Base Layers
Sub Zero Factor 1 Plus Unisex Long Sleeve Thermal Base Layers are manufactured from super soft 100% polyamide fabric produced on a seamless circular knitting machine. Utilising body mapping technology allows us to construct innovative seamless body forms and add features such as stretch rib zones for support and waffle zones for enhanced heat retention and greater perspiration control. All of our Factor 1 Plus seamless base layer tops have long body lengths to give you a decent amount of fabric to tuck in to your trousers, helping to avoid lower back exposure during activities.
The only seams present on these base layer thermal tops are on the sleeves and the shoulders where they incorporate other design features. The set-in sleeves provide a much more tailored fit in the armpits, maximising insulation and moisture transportation (wicking), whilst the seam on the sleeve length allows the addition of a thumb hole near to the cuff. This allows the wearer to place further layers on top of the base layer without the sleeves riding up, and can also protect the palm of the hand from cold weather. The round neck has been designed so that it stretches when placed over your head and its low profile also means it is not prominent when worn under clothing.
Sub Zero Factor 1 Plus unisex long sleeve seamless base layers are one of the best lightweight thermal underwear ranges for general outdoor use. The simple design makes them compatible with most sports where you need to keep warm and dry. They cross over in to anything from, skiing, through to hiking and camping, and can be used in combination with the Sub Zero Factor 2 thermal mid layer range for extra warmth in extreme conditions.

Great snug fit
I have been wearing these for a number of years now and they still like new. Their snug fit is comparable to a compression layer but a lot warmer.
